We have an external speaker that we plug into the usb on a hp laptop that we use for teams meetings. When this gets plugged into my bosses hp laptop it doesnt do anything, if we unplug it from computer then her computer speaker works fine wear you can hear and talk. I can take that same usb external speaker and plug it into my hp computer and it works just fine, we can hear and talk into. What would cause it not to work on her computer?
